  In the figure above, ifP Q R Sis a quadrilateral andT U Vis a triangle, what is the sum of the degree measures of the marked angles?

  (A)420 

  (B)490 

  (C)540 

  (D)560 

  (E)580 

  The correct answer is C

  Explanation

  The marked angles in the figure are anglesP,Q,R, andS, which are the angles of a quadrilateral, and anglesT,U, andV, which are the angles of a triangle. The sum of the degree measures of the angles of a quadrilateral is360, and the sum of the degree measures of the angles of a triangle is180. Therefore, the sum of the degree measures of the marked angles is360plus180, which is540.

  下面是一道和SAT官方每日一题相似的题目,供大家练习:

  If N times (5 over 14) = (5 over 14) times (7 over 9), then N =

  Answer Choices

  (A) 7 over 9

  (B) 9 over 7

  (C) 5

  (D) 7

  (E) 14

  The correct answer is A

  Explanation

  If N times (5 over 14) = (5 over 14) times (7 over 9), then by the commutative property of multiplication, N times (5 over 14) = (7 over 9) times (5 over 14). Multiplying each side of the latter equation by 14 over 5gives N times 1 = (7 over 9) times 1, so N = 7 over 9.
